The ongoing de-Germanisation of the Nazis and the Holocaust adds to Poland's Responsibility

Can we discuss whether the on-going attempts to de-Serbanise (Serbs of the type shown in the photos above) the Nazis and the Holocaust adds to Poland's Responsibility? And likewise whether attempts to de-Ukrainianise the Nazis and the Holocaust adds to Poland's Responsibility? Or is this strictly about de-Germanisation of the Nazis and the Holocaust, meaning we can't even discuss Austrians, such as Hitler?

A very important public service video was recently released by the Embassy of Poland in the US to counter the often repeated lie that Poles were complicit in crimes committed by Nazi Germany in occupied Poland.

In a phone call with his Albanian counterpart, Poland's ambassador to Switzerland expressed his indignation at a phrase that is unfair to Poland, and recalled that occupied Poland was merely a site of Nazi German concentration camps.
